TO WHOM IT MAY CONCER-N MMP VBe it known that I, WARREN J. NACE, of Tippecanoe City, Miami county, O hio, have invented a new and useful Stove-Pipe Scraper; and I hereby declare the following to be a full, clear, and. exact description'thereof, reference being hndto the accompanying drawing-s, making part of this speciiication.

My invention relates to a peouliarly-formed and arranged scraper, within abistove-pipe, for cleansing the interior of soot, ashes, or other accumulations.

Figure l is an axial section'of a 'stovepipe, 'within which my scraper is shown l in the act of disengaging and' removing the soot, 32,0.

Figure 2 represents the same, with the scraper being drawn back to its first position.

Figure 3 is a perspective View of the scraper detached.

A'is a vertical, and B o. horizontal portion of va stovefpipe, the said portions being joined bya; customary elbow, C. AD is ,a rod or stout wire passed diametrically through the pipe,` and terminating outside ofthe pipe in a crank, E.' The scraper proper consists of'a disk, F, which may be of cast or stout-sheet iron.v Attached to one part of the disk F is a weight, G, -in order to give -that part a preponderance, and give the disk a tend.

vency to assume a position transverse to the pipe. Projecting from the lightl or unloaded-side of the disk are two eyes or loops H H', for the engagement of a bail, I., for the attachment of a chain, J, that is carried out through the pipe-elbow.A Extending in a plane atright angles from the bail proper is a. bow, K, which, when the scraper is in operation, prevents the disk falling out of a vertical plane, and co-acts with the drag of the f chain on the bail, and with the weight upon the other portion of the disk, to maintain the disk in a. vertical position in the act of' scraping. Attached also. to thelight portion of the disk, but on the obverse side, is another chain, L, which, beingcarried forward in the pipe, has its other extremity made fast to, the rod D. The chain L being attached to the light portion ofthe disk, rotation ofthe rod acts to throw the'said disk'with its plane' nearly coincident with the, axis of the pipe, (see hg. 2,) and to draw itforward to close proximity with vthe rod,` whxere it remains in nearly horizontal position,1so as to afford an unobstructed passage for the smoke.

When it is desired to clear out the pipe, the operator .grasps the chain J and draws it through the hole in the pipe-elbow. v This draught on the chain causes the disk to assume the vertical position, so as to act as anl eeetive scraper to dislodge and remove the debris Aor accumulations. This having been effected, the disk is 'drawn back to its resting-position, as already stated.

I claim herein as new, and of my invention- ,r

The provision in a stove-pipe of' the crank-rod D, loaded disk F, bail I K, and chains kJ and L, the whole being arranged and adapted to operate as set forth.

In testimony of which invention I hereunto set my hand.`
